Rigid Shaft Coupling, 950 in-lb

The Ruland CLX-12-12-SS is a one-piece rigid shaft coupling made from stainless steel. It connects two shafts with identical 3/4 in round bores and transmits up to 950 in-lb of torque at speeds up to 4,000 RPM. The clamp-style design suits precision motion-control applications requiring zero backlash.

Bore and clearance check

Verify both shafts measure exactly 3/4 in diameter with round profiles before ordering. Confirm the 1.84 in clearance diameter fits inside your machine envelope and that no keyways are present on either shaft. The coupling accepts no bore-size variation and has no keyway slots machined into its bores.

Stainless steel and Prop 65

The stainless-steel construction provides corrosion resistance in wash-down or outdoor environments without additional coatings. A California Proposition 65 notice applies because the material contains a listed substance; handle accordingly during installation and maintenance. No lubricants, fasteners or alignment tools are included with the coupling.

Questions about this item

What components come with the CLX-12-12-SS coupling and is any hardware sold separately?

The one-piece stainless steel coupling arrives fully assembled with integral clamp screws; no additional fasteners or accessories are required for installation.

How do I decide between the available bore sizes for the CLX-12-12-SS?

This model has identical 3/4 in bores on both ends, so there is no choice to make — it connects two shafts of the same diameter.

What does the 950 in-lb torque rating mean when the coupling is mounted on a machine?

It indicates the maximum continuous twisting force the stainless steel body can transmit at up to 4,000 RPM without permanent deformation.
